In the small-cage experiments of 1905-6 but three localities were 

 tested. In the 26 experiments w^ere placed 4,211 weevils, of which

 where it would seem that such protection was least needed. The 

 two most striking results were the small survival at Dallas and the 

 remarkably large survival in one of the outdoor experiments at 

 Calvert. In the outdoor tests an average of 3.9 per cent survived,
